Introduction
SD3100 DC Power Modules convert fixed voltage and frequency three-phase AC
power to adjustable voltage DC power, which can be used to supply the armature or
field of a DC motor. An SD3100 Power Module operates within the AutoMax
Distributed Power System (DPS) environment, and is controlled by the AutoMax
Programming Executive software. The Power Module communicates with the AutoMax
system via an internally mounted Power Module Interface (PMI) rack, which contains
the drive’s control circuits and executes the motor control algorithm.
The SD3100 configuration provides control of DC motors, rated 700 to 2500 HP, with
current ratings of 1250, 1650, and 3000A. Input voltages of 460, 575, and 660 VAC
are available. Figure 1.1 shows the SD3100 catalog numbering scheme.

N = Non-regenerative, 6-pulse
R = Regenerative, 6-pulse
AA = NEMA Type 1 without gaskets and door fan filters
AJ = NEMA Type 1 with gaskets and door fan filters
B = 460 VAC
C = 575 VAC
F = 660 VAC
64 = 700 HP
65 = 750 HP
66 = 800 HP
67 = 900 HP 68 = 1000 HP
69 = 1250 HP
70 = 1500 HP
71 = 1750 HP 72 = 2000 HP
73 = 2250 HP
74 = 2500 HP
